Delphi是Windows平臺(tái)下高效的可視化集成開(kāi)發(fā)環(huán)境(IDE)，其具有所見(jiàn)即所得的可視化界面設(shè)計(jì)風(fēng)格和面向?qū)ο蟮某绦蛟O(shè)計(jì)等特點(diǎn)，已廣泛應(yīng)用于各個(gè)領(lǐng)域，成為首選開(kāi)發(fā)工具之一。Delphi提供了良好的界面設(shè)計(jì)能力，在PC機(jī)的串口通信方面也有很強(qiáng)的功能。
數(shù)據(jù)采集過(guò)程實(shí)質(zhì)上是信息的采集、傳遞和處理以及對(duì)數(shù)據(jù)采集器控制的過(guò)程。由于串行通信具有所用的傳輸線少,成本低,傳輸距離近等特點(diǎn)，現(xiàn)實(shí)中通常采用以PC機(jī)為主機(jī)，通過(guò)線纜連接,以RS232/485串行接口為通信通道，對(duì)數(shù)據(jù)采集器進(jìn)行控制，并接收采集到的數(shù)據(jù)和采集器的狀態(tài)信息。
2.串行通信方法簡(jiǎn)介
目前PC機(jī)普遍采用Microsoft 32位Windows操作系統(tǒng)。Windows下的串行通信不提倡應(yīng)用程序直接控制硬件，而是通過(guò)操作系統(tǒng)提供的設(shè)備驅(qū)動(dòng)程序來(lái)進(jìn)行數(shù)據(jù)傳遞，或者說(shuō)是通過(guò)系統(tǒng)提供的數(shù)據(jù)結(jié)構(gòu)與系統(tǒng)進(jìn)行信息交換，進(jìn)而完成數(shù)據(jù)的發(fā)送和接收。串行口在Win 32中是作為文件方式來(lái)處理的，Win32提供了相應(yīng)的文件I/O函數(shù)與通信函數(shù)。讀寫(xiě)串口的操作一般可以通過(guò)4種形式加以實(shí)現(xiàn)：查詢、同步I/O、異步I/O、事件驅(qū)動(dòng)I/O。查詢方式簡(jiǎn)單直接，但占用了大量的CPU時(shí)間；同步方式直到讀取到指定字節(jié)數(shù)或超時(shí)時(shí)才返回，應(yīng)用程序在程序結(jié)束前始終控制程序流，通信故障等因素可能會(huì)導(dǎo)致應(yīng)用程序的無(wú)限等待，從而長(zhǎng)時(shí)間阻塞線程；異步方式則在后臺(tái)讀寫(xiě)數(shù)據(jù)，而在前臺(tái)執(zhí)行其它任務(wù)；事件驅(qū)動(dòng)是在指定的串口事件發(fā)生時(shí)自動(dòng)調(diào)用相關(guān)的處理程序的機(jī)制。前兩種方法效率低、浪費(fèi)資源，因此一般使用異步I/O和事件驅(qū)動(dòng)I/O。
3.Delphi環(huán)境下串口通信實(shí)現(xiàn)方法
Delphi下編制串行通信程序，可利用Windows 標(biāo)準(zhǔn)API串行通信函數(shù)，也可利用為簡(jiǎn)化Windows下串行通信編程的ActiveX控件，如Microsoft Communications Control(MSComm)或者Delphi的第三方控件如Spcom來(lái)實(shí)現(xiàn)。前者程序設(shè)計(jì)相對(duì)復(fù)雜，不易掌握，但可以實(shí)現(xiàn)功能強(qiáng)大、應(yīng)用廣泛、復(fù)雜的低層次通信程序。而后者則相對(duì)簡(jiǎn)單，上手快，開(kāi)發(fā)工作量少。Delphi第三方控件是Object Pascal類，它遵循一定的規(guī)則，并通過(guò)面向?qū)ο蟮母拍畹靡岳^承和擴(kuò)充，為Delphi的應(yīng)用開(kāi)發(fā)提供了豐富的資源。 Delphi開(kāi)放式的控件支持環(huán)境，使得成千上萬(wàn)的Delphi用戶能夠?yàn)镈elphi編寫(xiě)大量的第三方控件，并通過(guò)Internet發(fā)布，形成巨大的共享資源。下面分別介紹利用API和第三方控件實(shí)現(xiàn)Delphi下串行通信的方法。
